High impact information on yl

  • Despite the presence of yolk within these oocytes, females homozygous for weak yl- alleles remain sterile, and their mature oviposited eggs collapse with time [1].
  • Female sterile (1) yolkless: a recessive female sterile mutation in Drosophila melanogaster with depressed numbers of coated pits and coated vesicles within the developing oocytes [1].
  • However, during oogenesis in yl mutants that express full-length protein yet fail to incorporate yolk proteins, the receptor remains evenly distributed throughout the oocyte [2].
  • RNA in situ hybridization and lacZ reporter analyses show that yl RNA is synthesized by the germ line nurse cells and then transported to the oocyte [2].
  • Mitochondria translocated into central yolkless cytoplasm, while mtlrRNA remained in the posterior cortex in the posterior muscle-lineage b astomeres [3].
